OTTI reports U.S. outbound travel monthly by all modes, expanding beyond air-only traffic. Total departure travel, inclusive of all modes, to Canada and Mexico is reported in addition to the air-only subtotals. The timing of this report is dependent on receipt of aggregate data from Stats Canada and Banco de Mexico.

(1) Overseas markets reflect non-stop air-only data. A portion of the non-stop passenger traffic to Europe will not visit Europe, but will connect through one of Europe's airline hubs (LHR, AMS, FRA, CDG, MAD, etc.) to Africa and the Middle East. The adjustment to these regions, reflecting visitation (1+ nights), occurs after year-end data is compiled.
